My father is an alcoholic. I've heard he's recovering now, though we haven't spoken in many years. My mom suffers from paranoid schizophrenia and used to self-medicate with MJ when I was growing up. She is also a Defcon level 5 codependent. Her schizophrenia has progressed to the point where she is basically codependent on the entire world.
I just left a relationship with an active alcoholic. Before that I was married to a man with what I suspect now was undiagnosed ADD. He was a compulsive liar and verbally, emotionally and, before he got sick, physically abusive to me. He died of cancer last July. I feel guilty about how glad I was (and still am) about his death, because our son is devastated, but I can't help it.
Thanks to everyone for sharing. And thanks to Justa. Great thread.
